DISAPPEARING WINDOW-BLIND.

Specification of Letters Patent- Patented Spt- 24, 19118..

Application filed October 30, 1916 Serial o. 128,6:4(

To all whom it may concern;

Be it known that I, BRADp Y Ron, a cit- 1 zen ofthe United States, reslding at Kansas City, in the county offJackson'andState of Missouri, have nvented certain new and useful Improveinents in Disappearing Window- Blinds, of whichthe following is a specification. This invention relates to Windowblinds, and has for its object to producea blind which is normally hidden from View, but

which, whenthe lower sash'of the windowv is raised, can" be caused'to fill or occupy the space vacated by such sash. A further ob ject is to. produce a. blind of the typ'e' ea tioned; proir'idejd with hinged slats suscepti bleof being adjusted to provide for thedesinedyentilation andlight.

Anotherobject is to provide a blind which will prevent rain or snow from entering 'a room protected by said blinds, and ineans cooperating with said, blind for draining from the building an'yfwateriwliich obtainsl access to the lower sash rail'of the blind.

lVith these'general objects in View, the

invention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described "and claimed; and in order that it may be fully understood reference is'to be had to the accompanyingdrawing, in which,

Figure 1,.is an inner face View, o'f'a roorn wall equipped with a blind embodying invention, the wall being broken away, to show the blind in the pocket, in said wall.

Fig. 2, is an" enlarged vertical section taken on theline II-'II of Fig. '1.' Fig. 3, is an enlarged horizontal section taken on the line III-III' of Fi' 1,' but.

showing the slatso-pen- Fig. 4, is a fragmentary Vertical section of the lower rail of the inner window Sash and the upper rail of the blind sash, to Show a lock carried by the window sash and'em gaging the blind sash to effect lifting and lowering movement of the latter by the former.

Referring to the said drawings in detail,

1 indicates the Wall of a building and 2 a window therein, the Wall containing a pocket '3, preferably slightly exceeding the depth of the lower sash of the window and at the bottorn of saidfpocket isa drainbox lhaying its bottorn sloping toward one end and pro- Vi-ded m' l fi con' irnunicating the fmi e wh p pieay servee as a drain pipe for windows of different floors, iflit be desired to equ'ipthe windows of the upper'floors with blinds of this char Corresponding inform, size andcontoun to the lower sash of the window directly:

acter,

under occupying the pocket S' or of filling thefspace liorrnallyioccupied byfthe said lower[ sash whenf'lo'wered, is a blind embodying" the in vention. "For a bungalow or the first floor of a building, it ispreferred that the blind] shall be of sheetsteel or analogous metal, as

' for such windows it 'willfserve a'protec tion against the entrance'of unauthorized pe'rsons',in the event the lower sash is raised for Ventilation by day Or night. 'This blind comprises a rectangular frame consisting of a bottom rail. 71a top rail 8 and 't wo side rails 9 connectingj the'topand bottonri rails;

The bottorn railis preferably provided, at its outer face with an upwardly projecting flange 11', andthe' upper wall of saidbottoin rail is depressed to forini a longitudinal jch an nel 12 pro vided with oneor' inore' holes V V The upper rail is provided at its outer edge with a depending rib ll'to overlapthe" upper end of the topmostof a series of slats 15, when the slats are in closed position, the

said'slats wlienin closed position occupying n d nw d y" a d utwa d y l e l'iiosi tron, w th'the l ower portio-n of each 'ovelr lapping the upper portion of the "adj acent f slat at the outer side thereof," itbeing noted 7 that the ends of the slats while spaced 1 slightly fro n the inner walls f the side rails 9, are substantially overlapped'by the fianges"l() so that water or snow cannot readily enter the space between the side walls and the ends of said slats.

'The lower ends" of 'the'slats are formed ru liio fwhic ext d r ugh h r" walls of the side rails of thesash andfa're" d pt t w re pew-1 y" h mnd formed "at or'near the"up per ends of the; lats a d p efe ab yhfie l t eretro e with "outwardly 1pr0jectingpiyot pins er;

by dotted lines in the same figure,

shown, are pivot pins 17, which pins extend pivotally through vertical links 18, arranged between the side walls of the sash and the ends of the slats. V

\Vhen the slats are in their closed or overlapping pOSitiOnS, the links 18 occupy the position shown in full lines, Fig. 2, and when the slats are fully opened as indicated by some of them in dotted lines in said figure, the links occupy the position shown it being understood in this connection that when the links occupy the last-named position, their lower extremities enter the channel 12 in the base rail of the sash, as without the provision of said channel or its equivalent, the lower ends of said links would come in contact with the lower rail of the sash and prevent the slats being opened to a horizontal position. For convenience in opening and closing the slats, the links 18 will preferably be provided at their inner edges with lugs 19, which can be conveniently grasped for their manipulation, especially when it is desired to swing the slats to open position, as at such time the slats themselves do not provide a convenient gripping surface.

In lieu of the gripping lugs 19, short angle plates 20 may be slidingly secured for vertical movement around the inner corners of the side rails of the sash, their inner arms fitting flatly between the inner walls of the side rails and the links 18, and provided with slots 21 receiving the ends of a pair of pivot pins 17 of the slats, so that when said angle plates are slid upward on the sash they will impart closing movement to the slats, the said pins 17 as they swing upward and outward, traveling toward the outer ends of the slots 21.

In order that the plates 20 shall not project beyond the inner face of the sash, the latter will preferably be provided with recesses 22 accommodating the plates, and in order that the latter may be conveniently moved upward and downward, the inner corners of the side rails of the sash for a distance slightly exceeding the length of the angle plates. plus their adjustment, are formed with channels 23, and the angle plates are provided at their corners with inwardly projecting lugs 241-, so that the operator in gripping the plates to adjust them and hence open or close the slats, will not. encounter any sharp or narrow edges tending to hurt or injure his fingers. Said plates will be secured in position with suffici ent friction to hold the slats in fully opened position or inany intermediate position between their fully opened or closed position, by means of guide screws 25 extending into the side ,rails through slots 26 infsaid angle plates. v

The upper surface of the top rail of the .weights, not shown,

blind, when occupying the pocket, will preferably constitute a part of the bottom of the window frame and therefore abut against the lower rail of the inner sash of the window when the said sash is lowered.

To raise the blind, the lower rail of the window sash will be provided with a catch for engagement with the upper rail of the blind, any suitable catch may be employed, that shown comprising a casing 27 set in the lower face of the sash of the window and provided with a cross shaft 28 extending beyond the inner face of said sash and provided at its inner end with an operating handle 29, and within the casing with a substantially semi-circular crank arm 30; said crank arm when the handle is turned being projected through an opening 31 in the botit is desired to operate the window sash 7 without raising the blind. The blind will preferably be equipped with counterbalance V of the type commonly used in window sashes, said weights being omitted as being of obvious application.

In the event water collects or runs down upon the lower rail of the'blind when the slats are closed or partly closed, it will enter the channel 12 and escape therefrom through the perforation l3, and then pass through similar perforation 33 in the lower wall of said rail, into the drain boX t and pass thence through tube 5 and pipe 6. It

will be apparent that a blind of this character will enable the occupant of a room to properly ventilate such room at night and yet guard against unauthorized entrance more effectually than the sash of the window. In the day time, the slats can be adjusted to provide the necessary ventilation and security as well as insure greater privacy, particularly if the window is on the first floor.

,From the above description it will be apparent that I have produced a window blind possessing the features of advantage enumerated as desirable in the statement of the object of the invention, and I Wish it to be understood that while I have illustrated and described what now appears to be the preferred form of the invention, I reserve the right to make all changes falling within the spirit and scope of the appended claim.

I claim In a disappearing window blind structure, a frame fitting in a pocket in a wall, the sides of the frame having vertical channels in their inner corners, a series of horizontal slats extending across the frame from sides and horizontal play connection with one side thereof to the other and pivoted said series of slats. 10 at their ends to said sides, said slaxts having In testimony whereof, I afi'ix my signaa vertical series of horizontal end pins, links ture, in the presence of two Witnesses.

pivotally connecting the said end pins, and BRADLEY ROE. right-angle corner plates fitting slidingly on WVitnesses:

the sides over said channels in the latter, H. O. RODGERS,

and having vertical play connection with said G. Y. THORPE.
